Uh, I think we're talking past each other (and apologies to the list 
if this discussion is getting a bit obscure). CFWS *is* optional in 
group. Here's all of the syntax in question:

group           =   display-name ":" [group-list] ";" [CFWS]
display-name    =   phrase
group-list      =   mailbox-list / CFWS / obs-group-list
mailbox-list    =   (mailbox *("," mailbox)) / obs-mbox-list

So, in the generate syntax, group-list is optional in group, and may 
contain either a mailbox-list or CFWS.

Now, here's my new obs-mailbox syntax:

obs-mbox-list   =   *([CFWS] ",") mailbox *("," [mailbox / CFWS])

The only thing not described by the above is a mailbox list with no 
mailboxes at all (i.e., simply commas with optional surrounding 
CFWS). That's:

obs-group-list  =   1*([CFWS] ",") [CFWS]

I'm happy to simplify if possible. But so far, that's the best I can do.
